Nuclear Instrumentation & Controls Engineer

The role

This engineer will support the development, integration, testing, and qualification of nuclear measurement systems and reactor instrumentation. They will design and operate test platforms and develop automated testing capabilities for various reactor components.

What you will do

• Collaborate with multidisciplinary engineering teams to develop and qualify nuclear instrumentation and control systems.
• Design, build, and operate hardware-in-the-loop test platforms and automated test stands.
• Develop and execute test plans for neutron detectors, electronics, and other reactor instrumentation.
• Perform sensor characterization, calibration, and performance testing.
• Design and execute environmental qualification testing involving radiation, thermal, vacuum, vibration, and shock.
• Develop and maintain automated test software interfacing with data acquisition systems.
• Translate engineering requirements into test objectives, procedures, and verification activities.
• Analyze test data, investigate anomalies, and document findings in technical reports.
• Support instrumentation architecture development and vendor selection.

Required qualifications

• Bachelor's degree in Nuclear Engineering, Electrical Engineering, Physics, Systems Engineering, or a related technical discipline.
• 4+ years of experience developing, integrating, or testing instrumentation and control systems in nuclear, aerospace, defense, or other high-reliability applications.
• Hands-on experience with sensors, measurement electronics, calibration, data acquisition systems, and automated instrumentation testing.
• Proficiency in Python programming for automated test execution, data acquisition, and analysis.
• Strong technical communication skills for writing test plans, procedures, and reports.
• Ability to operate in a dynamic startup environment with high ownership and hands-on execution.
• Ability to work long hours and weekends as necessary to support critical milestones.

Nice to have

• Experience with neutron detectors, nuclear measurement systems, radiation-source testing, neutron detector calibration, or nuclear reactor operations.
• Experience designing and operating environmental test equipment including thermal chambers, vacuum systems, vibration tables, shock fixtures, and radiation test facilities.
• Experience with spaceflight hardware qualification, radiation effects on electronics, or environmental testing for aerospace applications.
• Experience developing test systems using National Instruments, LabJack, or similar data acquisition hardware, including serial and Ethernet interfaces, C/C++, or programmable logic controllers.
• Experience developing human-machine interfaces for reactor operations, integrating instrumentation with reactor control systems, or verifying coupled sensor-electronics systems.

Before you apply

• Applicant must be a U.S. citizen or national, U.S. lawful permanent resident, Refugee, or Asylee, or be eligible to obtain required authorizations from the U.S. Department of State.
